In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. It will be readily apparent however, that the present disclosure may be practiced without limitation to these specific details. In other instances, some methods and structures have not been described in detail so as not to unnecessarily obscure the present disclosure.

Throughout the present disclosure, the terms “a” and “an” are intended to denote at least one of a particular element. As used herein, the term “includes” means includes but not limited to, the term “including” means including but not limited to. The term “based on” means based at least in part on.

Decentralized supply chain for three-dimensional printing based on distributed ledger technology systems, methods for implementing a decentralized supply chain for three-dimensional printing based on distributed ledger technology, and non-transitory computer readable media having stored thereon machine readable instructions for decentralized supply chain for three-dimensional printing based on distributed ledger technology are disclosed herein. The systems, methods, and non-transitory computer readable media disclosed herein provide a supply chain for digital inventory of electronic three-dimensional printing files, such as stereolithography files, G-Codes, etc., that may be used in three-dimensional printing with distributed ledger technology. The electronic three-dimensional printing files may be creations and intellectual property assets that are transacted with multiple members throughout a supply chain. In this regard, management of the electronic three-dimensional printing files as digital inventory by transacting permission for access rights on a permissioned or private distributed ledger framework enables the complete control and visibility of the supply chain of such files. The systems, methods, and non-transitory computer readable media disclosed herein may provide for the management of multiple transactions of ownership, secure delivery and usage of electronic three-dimensional printing files, access based control to the electronic three-dimensional printing files, and visibility across a supply chain for stakeholders. Further, the systems, methods, and non-transitory computer readable media disclosed herein may provide for the management of time-stamped transaction and electronic three-dimensional printing file usage data, and automated execution of funds transfer for different payment cycles and entities. These aspects may be implemented by the systems, methods, and non-transitory computer readable media disclosed herein in a framework without the need for a third party or central authority. The systems, methods, and non-transitory computer readable media disclosed herein provide a platform for manufacturing from digital inventory with trust and traceability among corporations and other entities barring any geographical boundaries.

With respect to electronic three-dimensional printing files, the systems, methods, and non-transitory computer readable media disclosed herein provide a digital inventory management system for such files. In this regard, given the rapid technical advancement in the field of three-dimensional printing, the portfolio of printable parts continues to grow. For the systems, methods, and non-transitory computer readable media disclosed herein, parts that may be printable using a three-dimensional printer may be identified by a printability analyzer as disclosed herein. A print evaluator may analyze costs of materials, cost of operations and printers, which may translate to a higher number of three-dimensional parts where there is a potential for savings. Further, a digital integrator may be built over a blockchain network, which may operate as a distributed electronic ledger to provide for tracking and tracing of a print job and associated electronic three-dimensional printing files. In this regard, the digital integrator and the distributed electronic ledger may provide a complete inventory management solution for three-dimensional printed parts. The decentralized ledger technology may provide for properties such as traceability, immutability of transaction data, provenance of electronic three-dimensional printing files, and security of electronic three-dimensional printing files. The digital inventory management provided by the systems, methods, and non-transitory computer readable media disclosed herein may also provide for augmentation of manufacturing, logistics, and warehousing management.

With respect to technical challenges associated with management of electronic three-dimensional printing files, in the area of manufacturing, it is technically challenging to manage the manufacture of parts that may utilize electronic three-dimensional printing files, such as stereolithography files, G-Codes, etc. For example, it is technically challenging to ascertain an electronic three-dimensional printing file to avoid delays with respect to manufacture of a three-dimensional part. For parts that may be manufactured by the hundreds or thousands, it is technically challenging to manage, for example, from a remote location, use of electronic three-dimensional printing files to ensure that the files are authorized for use. In this regard, once an electronic three-dimensional printing file is being used, it is technically challenging to manage, for example, from a remote location, use of the electronic three-dimensional printing file to ensure that an associated three-dimensional part is being manufactured according to the specifications of the electronic three-dimensional printing file. It is also technically challenging to determine whether a three-dimensional part may be manufactured by a three-dimensional printing technique, and whether the part should be manufactured by a three-dimensional printing technique. It is also technically challenging to determine the misuse of a three-dimensional part. It is also technically challenging to segregate from hundred thousand of part data into printable and non-printable parts. It is also technically challenging to operate multiple hardware devices in one platform as different three-dimensional printers may use different software. It is also technically challenging to determine when the three-dimensional parts are printed and ready for collection. It is also technically challenging to provide a single dashboard of multiple three-dimensional printers located at various locations on real-time basis. Yet further, it is also technically challenging to ascertain live printing of three-dimensional parts from a remote location.

In order to address at least the aforementioned technical challenges with respect to manufacture of three-dimensional parts, and management of electronic three-dimensional printing files, the systems, methods, and non-transitory computer readable media disclosed herein provide a printability analyzer to ascertain, from an electronic three-dimensional printing file for a three-dimensional part to be printed, three-dimensional printing constraints that include a design constraint, a material constraint, and a dimension constraint. The printability analyzer may ascertain a plurality of attributes for each three-dimensional printer of a plurality of three-dimensional printers that may be used to manufacture the three-dimensional part. The printability analyzer may compare the three-dimensional printing constraints from the electronic three-dimensional printing file for the three-dimensional part to be printed to each attribute of the plurality of attributes for each three-dimensional printer of the plurality of three-dimensional printers. For example, the plurality of attributes may include a design attribute, a material attribute, and a dimension attribute associated with each of the three-dimensional printers. The printability analyzer may determine, based on the comparison, whether the three-dimensional part is printable by at least one three-dimensional printer of the plurality of three-dimensional printers or not printable by any three-dimensional printer of the plurality of three-dimensional printers. A print evaluator may ascertain, based on a determination that the three-dimensional part is printable by the at least one three-dimensional printer of the plurality of three-dimensional printers, costs (e.g., non-three-dimensional printing based manufacturing costs and three-dimensional printing costs) associated with three-dimensional printing of the three-dimensional part and non-three-dimensional printing based manufacturing of the three-dimensional part. The print evaluator may determine, based on an analysis of the costs associated with the three-dimensional printing of the three-dimensional part and the non-three-dimensional printing based manufacturing of the three-dimensional part, whether the three-dimensional part to be printed by the at least one three-dimensional printer of the plurality of three-dimensional printers is economically cheaper than the part produced by non-three dimensional printing. A digital integrator may ascertain, based on a determination that the three-dimensional part is to be printed by the at least one three-dimensional printer of the plurality of three-dimensional printers, the electronic three-dimensional printing file for the three-dimensional part to be printed. The digital integrator may control, by a distributed electronic ledger, execution of the electronic three-dimensional printing file for the three-dimensional part to be printed. The digital integrator may control, by the distributed electronic ledger and based on the execution of the electronic three-dimensional printing file for the three-dimensional part to be printed, printing of the three-dimensional part. In this regard, misuse of a three-dimensional part may be prevented by transferring the associated file over a secured distributed ledger system as disclosed herein.

The printability analyzer may thus analyze hundreds or thousands of three-dimensional parts in a single analysis. The printability analyzer may provide intelligent printer selection by comparing specification of hundreds or thousands of three-dimensional printers. The printability analyzer may determine a most appropriate material selection by analyzing detail material properties for a three-dimensional part. The printability analyzer may generate an output that includes multiple three-dimensional parts that may be categorized into printable and non-printable parts on the basis of material, dimension, and design parameters. The printability analyzer may provide three-dimensional printer suggestions for printable parts. Further, the printability analyzer may provide material recommendation for non-printable parts in the event such parts are not printable due to material constraints.

The print evaluator may thus evaluate a plurality of cost factors to compare printing of the three-dimensional part using three-dimensional printing and non-three-dimensional printing based manufacturing. The print evaluator may also implement a volumetric analysis to provide a cost for a three-dimensional part using three-dimensional printing and non-three-dimensional printing at different volume points.

In some examples, elements of the decentralized supply chain for three-dimensional printing based on distributed ledger technology system may be machine readable instructions stored on a non-transitory computer readable medium. In this regard, the decentralized supply chain for three-dimensional printing based on distributed ledger technology system may include or be a non-transitory computer readable medium. In some examples, the elements of the decentralized supply chain for three-dimensional printing based on distributed ledger technology system may be hardware or a combination of machine readable instructions and hardware.

The printability analyzer 102 may determine, based on the comparison, whether the three-dimensional part 106 is printable by at least one three-dimensional printer 114 of the plurality of three-dimensional printers 112 or not printable by any three-dimensional printer of the plurality of three-dimensional printers 112.

According to examples disclosed herein, the printability analyzer 102 may determine, based on the comparison, whether the three-dimensional part 106 is printable by the at least one three-dimensional printer 114 of the plurality of three-dimensional printers 112 or not printable by any three-dimensional printer of the plurality of three-dimensional printers 112 by determining whether the design attribute meets or exceeds the design constraint, determining whether the material attribute meets or exceeds the material constraint, and determining whether the dimension attribute meets or exceeds the dimension constraint.

According to examples disclosed herein, based on a determination that the three-dimensional part 106 is not printable by any three-dimensional printer of the plurality of three-dimensional printers 112, the printability analyzer 102 may determine whether the design constraint or the material constraint of the three-dimensional part 106 to be printed is not respectively met by a design attribute or a material attribute of any three-dimensional printer of the plurality of three-dimensional printers 112. Further, based on a determination that the design constraint of the three-dimensional part 106 to be printed is not met by the design attribute of any three-dimensional printer of the plurality of three-dimensional printers 112, the printability analyzer 102 may specify a redesign for the three-dimensional part 106 to be printed to meet the design attribute of at least one three-dimensional printer 114 of the plurality of three-dimensional printers 112.

Further, based on a determination that the material constraint of the three-dimensional part 106 to be printed is not met by the material attribute of any three-dimensional printer of the plurality of three-dimensional printers 112, the printability analyzer 102 may specify an alternate material for the three-dimensional part 106 to be printed to meet the material attribute of at least one three-dimensional printer of the plurality of three-dimensional printers 112.

A print evaluator 116 that is executed by at least one hardware processor (e.g., the hardware processor 2302 of FIG. 23, and/or the hardware processor 2504 of FIG. 25) may ascertain, based on a determination that the three-dimensional part 106 is printable by the at least one three-dimensional printer 114 of the plurality of three-dimensional printers 112, costs (e.g., non-three-dimensional printing based manufacturing costs 118 and three-dimensional printing costs 120) associated with three-dimensional printing 122 of the three-dimensional part 106 and non-three-dimensional printing based manufacturing 124 of the three-dimensional part 106.

The print evaluator 116 may determine, based on an analysis of the costs associated with the three-dimensional printing 122 of the three-dimensional part 106 and the non-three-dimensional printing based manufacturing 124 of the three-dimensional part 106, whether the three-dimensional part 106 is to be printed by the at least one three-dimensional printer 114 of the plurality of three-dimensional printers 112.

According to examples disclosed herein, the print evaluator 116 may determine, based on the analysis of the costs associated with three-dimensional printing 122 of the three-dimensional part 106 and the non-three-dimensional printing based manufacturing 124 of the three-dimensional part 106, whether the three-dimensional part 106 is to be printed by the at least one three-dimensional printer 114 of the plurality of three-dimensional printers 112 by determining whether a cost associated with three-dimensional printing 122 of the three-dimensional part 106 is lower than a cost associated with the non-three-dimensional printing based manufacturing 124 of the three-dimensional part 106. Further, based on a determination that the cost associated with three-dimensional printing 122 of the three-dimensional part 106 is lower than the cost associated with the non-three-dimensional printing based manufacturing 124 of the three-dimensional part 106, the print evaluator 116 may determine that the three-dimensional part 106 is to be printed by the at least one three-dimensional printer 114 of the plurality of three-dimensional printers 112.

A digital integrator 126 that is executed by at least one hardware processor (e.g., the hardware processor 2302 of FIG. 23, and/or the hardware processor 2504 of FIG. 25) may ascertain, based on a determination that the three-dimensional part 106 is to be printed by the at least one three-dimensional printer 114 of the plurality of three-dimensional printers 112, the electronic three-dimensional printing file 104 for the three-dimensional part 106 to be printed.

The digital integrator 126 may control, by a distributed electronic ledger 128, execution of the electronic three-dimensional printing file 104 for the three-dimensional part 106 to be printed.

According to examples disclosed herein, the distributed electronic ledger 128 may include a blockchain network.

The digital integrator 126 may control, by the distributed electronic ledger 128 and based on the execution of the electronic three-dimensional printing file 104 for the three-dimensional part 106 to be printed, printing of the three-dimensional part 106.

According to examples disclosed herein, the digital integrator 126 may control, by the distributed electronic ledger 128, execution of the electronic three-dimensional printing file 104 for the three-dimensional part 106 to be printed by ascertaining an authorization to execute the electronic three-dimensional printing file 104 for the three-dimensional part 106 to be printed. The digital integrator 126 may determine, based on the ascertained authorization, whether an entity associated with the at least one three-dimensional printer 114 of the plurality of three-dimensional printers 112 is authorized to execute the electronic three-dimensional printing file 104 for the three-dimensional part 106 to be printed. Further, based on a determination that the entity associated with the at least one three-dimensional printer 114 of the plurality of three-dimensional printers 112 is authorized to execute the electronic three-dimensional printing file 104 for the three-dimensional part 106 to be printed, the digital integrator 126 may cause the electronic three-dimensional printing file 104 to be executed to print the three-dimensional part 106.

According to examples disclosed herein, the digital integrator 126 may control, by the distributed electronic ledger 128, execution of the electronic three-dimensional printing file 104 for the three-dimensional part 106 to be printed by ascertaining a material that is available for printing of the three-dimensional part 106. The digital integrator 126 may determine, based on the ascertained material that is available for printing of the three-dimensional part 106, whether an entity associated with the at least one three-dimensional printer 114 of the plurality of three-dimensional printers 112 has access to the material that is available for printing of the three-dimensional part 106. Further, based on a determination that the entity associated with the at least one three-dimensional printer 114 of the plurality of three-dimensional printers 112 has access to the material that is available for printing of the three-dimensional part 106, the digital integrator 126 may cause the electronic three-dimensional printing file 104 to be executed to print the three-dimensional part 106.

According to examples disclosed herein, the digital integrator 126 may control, by the distributed electronic ledger 128 and based on the execution of the electronic three-dimensional printing file 104 for the three-dimensional part 106 to be printed, payment to an owner of the electronic three-dimensional printing file 104 by the digital integrator 126 by determining, by the distributed electronic ledger 128, that the electronic three-dimensional printing file 104 has been executed. Further, based on a determination, by the distributed electronic ledger 128, that the electronic three-dimensional printing file 104 has been executed, the digital integrator 126 may cause, by the distributed electronic ledger 128, transfer of the payment to the owner of the electronic three-dimensional printing file 104.

Further, based on a determination, by the distributed electronic ledger 128, that the three-dimensional part 106 has been printed, the digital integrator 126 may cause, by the distributed electronic ledger 128, transfer of the three-dimensional part 106 to the user.

FIG. 2 illustrates further details of the architecture of the system 100, according to an example of the present disclosure.

Referring to FIGS. 1 and 2, a three-dimensional part 106 may include hundreds or thousands of components that may need to be maintained in an inventory management system. The system 100 may provide for such inventory management with respect to management of electronic three-dimensional printing files for three-dimensional parts to be printed.

The electronic three-dimensional printing files may generally include stereolithography (STL) files, and other such files. An STL file may be described as a file format used for stereolithography computer aided design (CAD) software.

With respect to the printability analyzer 102 and the print evaluator 116, a determination as to whether a three-dimensional part may be printed by a three-dimensional printer and a determination of whether a three-dimensional part should be printed by a three-dimensional printer may be respectively made with or without electronic three-dimensional printing files. In this regard, the determination by the printability analyzer 102 and the print evaluator 116 may be made with part information such as design constraints, material constraints, dimension constraints, etc., or by using an available electronic three-dimensional printing file. In this regard, instead of entering the three-dimensional printing constraints 108, the electronic three-dimensional printing file 104 for the three-dimensional part may be uploaded into the printability analyzer 102. The electronic three-dimensional printing file 104 may also include part information for a plurality of other parts, in addition to the three-dimensional part 106 that is to be printed.

With respect to the digital integrator 126, if an electronic three-dimensional printing file 104 is available from the printability analyzer 102 and/or the print evaluator 116, the electronic three-dimensional printing file 104 may be transferred to the digital integrator 126. If an electronic three-dimensional printing file 104 is not available from the printability analyzer 102 and/or the print evaluator 116, the electronic three-dimensional printing file 104 may be received, for example, from sources such as suppliers (e.g., the Supplier-1 and/or the Supplier-2 of FIG. 2), original equipment manufacturers 200, manufacturers 202, etc. For example, the original equipment manufacturers 200 may include a company designated XYZ corporation that provides for three-dimensional printing of thousands of parts. In this regard, the XYZ corporation may provide electronic three-dimensional printing files for such parts to be utilized by the digital integrator 126 as disclosed herein. That is, the electronic three-dimensional printing files may be made available to the distributed electronic ledger 128. Assuming that the three-dimensional part 106 to be printed corresponds to an electronic three-dimensional printing file 104 provided by the XYZ corporation, the electronic three-dimensional printing file 104 may thus be utilized by the digital integrator 126 to print the three-dimensional part 106 as disclosed herein. Once the three-dimensional part 106 has been printed, as shown in FIG. 2, the XYZ corporation may be paid by a bank 204 or otherwise remitted for usage for the electronic three-dimensional printing file 104. In the event an electronic three-dimensional printing file 104 is not available, a three-dimensional part may be scanned, for example, by the digital integrator 126 to create an electronic three-dimensional printing file 104.

With respect to the printability analyzer 102, referring to FIGS. 1 and 2, and particularly to FIG. 2, according to an example, an automobile company, or another such company, may include hundreds of thousands of three-dimensional parts that are manufactured and subsequently assembled. A three-dimensional part may be analyzed to determine whether the three-dimensional part is printable or not printable as disclosed herein. That is, a three-dimensional part may be analyzed and categorized as printable or not printable as disclosed herein. The design, material, and dimension constraints with respect to a three-dimensional part may be entered manually (e.g., as disclosed herein with respect to FIGS. 9-11. Additionally or alternatively, an electronic three-dimensional printing file 104 (e.g., a stereolithography file) for the three-dimensional part may be uploaded as shown in FIG. 2 at 206. Additionally or alternatively, the printability analyzer 102 may be integrated with a Product lifecycle management (PLM) and/or an Enterprise resource planning (ERP) system as shown at 208 to ascertain three-dimensional part information, such as an electronic three-dimensional printing file 104.

A PLM system may be described as an information management system for integrating different aspects of an enterprise. Examples of such aspects may include data, processes, people, etc. Further, an ERP system may be described as the integrated management of processes related to a corporation, where the management may be based on the collection, storage, and interpretation of data from the various activities of the corporation.

For the printability analyzer 102, as disclosed herein, the three-dimensional printing constraints 108 may include three-dimensional part information such as part identification (ID), design constraints, material constraints for the part, dimensions, etc. The material constraints may be known, or selected from a drop-down menu as disclosed herein. Based on an analysis of these three-dimensional printing constraints 108, the printability analyzer 102 may determine whether a part is printable or not printable as disclosed herein, and illustrated at 210 of FIG. 2.

The output of the printability analyzer 102 may include information with respect to the printer specifics (e.g., name, location, manufacturer, etc.), for the three-dimensional printer 114 that is to print the three-dimensional part 106.

The printability analyzer 102 may thus analyze a single three-dimensional part or thousands of three-dimensional parts, for example, included in electronic three-dimensional printing files, determine for each of the three-dimensional parts whether they are printable or not printable, implement intelligent printer selection that includes the comparison of a relatively large number of printers, and the most appropriate material selection by analyzing detailed material properties.

With respect to printability analysis at 212 performed by the printability analyzer 102, the printability analysis may compare the design constraints, the material constraints, and the dimension constraints for the three-dimensional part 106 to be printed with three-dimensional printer attributes 110 for a plurality of three-dimensional printers 112. In this regard, a three-dimensional printer may include attributes such as the type of design that may be printed (e.g., with or without holes, thin parts, etc.), the type of material that may be used, and the size of a three-dimensional part that may be printed. These attributes may be respectively compared to the corresponding design constraints, material constraints, and dimension constraints for the three-dimensional part 106 to determine whether the attributes are met or not met. For example, if the three-dimensional part 106 includes holes, but a three-dimensional printer is not capable of printing holes, then the three-dimensional printer may be removed from further consideration for printing the three-dimensional part 106 (unless the design constraints are modified as also disclosed herein). Similarly, other three-dimensional printers that are capable of printing holes may be retained for further consideration for printing the three-dimensional part 106. Moreover, if no available three-dimensional printer is capable of printing the three-dimensional part 106, then the three-dimensional part 106 may be classified at 214 as a non-printable part in the non-printable parts category.

Once the three-dimensional part 106 is classified as a non-printable part, at 216, the printability analyzer 102 may determine whether the three-dimensional part 106 is not-printable due to material requirements or due to design requirements. In this regard, with respect to material requirements, at 218, the printability analyzer 102 may determine which material constraint (e.g., Iron material) is the cause of the non-printable classification, and ascertain, for example, based on an analysis of equivalent three-dimensional printing materials, equivalent materials (e.g., Titanium) that may be used. At 218, the printability analyzer 102 may output such equivalent materials as alternate printable material suggestions. A user of the system 100 may be prompted to approve or reject the alternate printable material suggestions.

Similarly, with respect to design requirements, the printability analyzer 102 may determine which design requirement is the cause of the non-printable classification, and ascertain, for example, based on an analysis of equivalent three-dimensional printing designs, modifications to the design of the three-dimensional part 106. At 218, the printability analyzer 102 may output such a design modification as a redesign of the three-dimensional part. A user of the system 100 may be prompted to approve or reject the redesign of the part.

With respect to the print evaluator 116, the print evaluator 116 may determine whether, for a three-dimensional part that is determined as printable, the three-dimensional part should be printed. In this regard, at 220, the print evaluator 116 may determine an approximate cost of the three-dimensional part based, for example, on three-dimensional printing (illustrated in FIG. 2 as “additive manufacturing (AM)”) versus non-three-dimensional printing based manufacturing (illustrated in FIG. 2 as “traditional manufacturing (TM)”). For example, the non-three-dimensional printing based manufacturing may include traditional manufacturing in an environment that uses machines, other than three-dimensional printers.

The print evaluator 116 may receive three-dimensional part specific details such as the material for a three-dimensional part, total part weight, etc. At 222, the print evaluator 116 may further receive details with respect to non-three-dimensional printing based manufacturing techniques and costs (e.g., the non-three-dimensional printing based manufacturing costs 118) for the three-dimensional part, such as, material costs, labor costs, machine efficiency, the timelines associated with the non-three-dimensional printing based manufacturing techniques, etc. At 224, the print evaluator 116 may also receive details with respect to the three-dimensional printing costs (e.g., the three-dimensional printing costs 120) for the three-dimensional part, including the type of three-dimensional technology being used, the timelines associated with the three-dimensional printing, etc.

According to examples, the three-dimensional printing costs 120 may be based on factors such as cost of post processing due to material, machine maintenance, three-dimensional printing design cost, three-dimensional printing material cost, mold maintenance cost, post processing cost, three-dimensional printing machine running time in a day in hours, etc. Each of these factors may be weighted, for example, as a percent weight to determine the total three-dimensional printing costs 120.

According to examples, the print evaluator 116 may determine a monthly demand as follows:

-   -   (total number of parts to be produced)/(timeline in months)

The print evaluator 116 may determine a number of three-dimensional printers needed as follows:

-   -   (monthly demand/30)/(three-dimensional printers running time in         a day in hours/printing time of 1 part in hours)

For the three-dimensional printing costs 120, the print evaluator 116 may apportion the cost of three-dimensional printers as follows:

-   -   (cost of three-dimensional printer/number of three-dimensional         parts made of the same material)×number of three-dimensional         printers needed

For the three-dimensional printing costs 120, the print evaluator 116 may determine a material cost as follows:

-   -   per kg cost of material×weight of three-dimensional parts to be         produced in Kgs×total number of three-dimensional parts to be         produced

For the three-dimensional printing costs 120, the print evaluator 116 may determine an energy cost as follows:

-   -   hourly per unit cost of energy in three-dimensional printing         facility×printing time in hours×total number of         three-dimensional parts to be produced

For the three-dimensional printing costs 120, the print evaluator 116 may determine a design cost as input by a user.

For the three-dimensional printing costs 120, the print evaluator 116 may determine a post processing cost as follows:

-   -   labor hourly wage rate×total number of three-dimensional parts         to be produced×post processing time for a unit in hours

For the three-dimensional printing costs 120, the print evaluator 116 may determine a three-dimensional printer maintenance cost as provided by a printer manufacture, or specified as approximately 5% of printer cost per year.

For the three-dimensional printing costs 120, the print evaluator 116 may determine a training cost as follows:

-   -   training cost for 5-10 employees who can operate and maintain         three-dimensional printers

For the non-three-dimensional printing based manufacturing costs 118, the print evaluator 116 may determine a design cost, which may be input by a user.

For the non-three-dimensional printing based manufacturing costs 118, the print evaluator 116 may determine part material cost as follows:

-   -   total number of three-dimensional parts produced×weight of the         three-dimensional part to be produced in Kgs×per kg cost of         material×usage of material/weight of the three-dimensional part         to be produced in Kgs

For the non-three-dimensional printing based manufacturing costs 118, the print evaluator 116 may determine molding labor costs as input by a user.

For the non-three-dimensional printing based manufacturing costs 118, the print evaluator 116 may determine a mold maintenance cost as input by a user, or approximated as a percentage cost of mold cost.

For the non-three-dimensional printing based manufacturing costs 118, the print evaluator 116 may determine a post processing cost as follows:

-   -   total number of three-dimensional parts to be produced×labor         hourly wage rate×post processing time for unit in hours

For the non-three-dimensional printing based manufacturing costs 118, the print evaluator 116 may determine inventory carrying costs as follows:

-   -   cost of capital+obsolescence cost

For the non-three-dimensional printing based manufacturing costs 118, the print evaluator 116 may determine any expediting cost as input by a user.

Based on the foregoing, the print evaluator 116 may determine the total three-dimensional printing costs 120 as follows:

-   -   cost of three-dimensional printers+material cost+energy         cost+design cost+post processing cost+three-dimensional printer         maintenance cost+training

Based on the foregoing, the print evaluator 116 may determine the total non-three-dimensional printing based manufacturing costs 118 as follows:

-   -   design cost+mold cost+part material cost+molding labor cost+mold         maintenance cost+post processing cost+inventory carrying         costs+expediting cost

Based on the foregoing, the print evaluator 116 may determine the per part three-dimensional printing costs 120 as follows:

-   -   total cost using three-dimensional printing/total number of         three-dimensional parts to be produced

Based on the foregoing, the print evaluator 116 may determine the per part non-three-dimensional printing based manufacturing costs 118 as follows:

-   -   total cost using non-three-dimensional printing based         manufacturing/total number of three-dimensional parts to be         produced

Referring again to FIG. 2, at 226, based on the costs associated with the non-three-dimensional printing based manufacturing techniques and the three-dimensional printing, the print evaluator 116 may determine whether the three-dimensional printing is a cost-effective option (e.g., if AM<TM, then select three-dimensional printing).

As disclosed herein with respect to FIGS. 14 and 21, the print evaluator 116 may also conduct a volumetric analysis that provides a break-even point up to which the three-dimensional printing would be a more cost effective option, whereas beyond the break-even point, the non-three-dimensional printing based manufacturing techniques would be a more cost effective option.

The costs for the three-dimensional printing may differ from the costs for the non-three-dimensional printing based manufacturing techniques in that for the three-dimensional printing, the costs may include utilization fees associated with electronic three-dimensional printing files, costs associated with usage of a three-dimensional printer, and costs associated with transfer of a printed part from the three-dimensional printer to a purchaser. Whereas, for non-three-dimensional printing based manufacturing techniques, the costs may include costs for components used for the non-three-dimensional printing based manufacturing techniques, factory costs for the non-three-dimensional printing based manufacturing techniques, labor costs for the non-three-dimensional printing based manufacturing techniques, and further costs associated with transfer of a manufactured part from the manufacturer to the purchaser. Thus, logistics costs such as warehousing, etc., associated with non-three-dimensional printing based manufacturing techniques may not be applicable to the three-dimensional printing costs.

At 228, if it is determined that the three-dimensional printing is not a cost effective option (e.g., AM>TM), then the print evaluator 116 may perform a case-by-case analysis to determine whether the three-dimensional part 106 should be printed by three-dimensional printing or by manufactured by non-three-dimensional printing based manufacturing. For example, at 230, the print evaluator 116 may evaluate supply chain and performance benefits with respect to three-dimensional printing versus non-three-dimensional printing based manufacturing. At 232, if the benefits of three-dimensional printing are greater than the costs of three-dimensional printing, then the print evaluator 116 may determine that the three-dimensional part is to be manufactured by three-dimensional printing, and otherwise, at 234, non-three-dimensional printing based manufacturing may be used to manufacture the three-dimensional part.

With respect to the digital integrator 126, once the three-dimensional part 106 is identified as being printable by a three-dimensional printer, and determined as being a viable three-dimensional part that should be printed by a three-dimensional printer, the digital integrator 126 may control the printing with respect to the three-dimensional part 106. In this regard, the digital integrator 126 may determine which platform may be used to print the three-dimensional part 106, where the three-dimensional part 106 may be printed, when the three-dimensional part 106 may be printed, etc. The digital integrator 126 may securely print the three-dimensional part 106. In this regard, the digital integrator 126 may control operation of a three-dimensional printer that is to print the three-dimensional part 106. Further, the digital integrator 126 may control access to the electronic three-dimensional printing file 104 associated with the three-dimensional part 106.

If an electronic three-dimensional printing file is not available, the digital integrator 126 may control scanning of the three-dimensional part 106. For example, the digital integrator 126 may control scanning of the three-dimensional part 106 by controlling or otherwise performing scanning of a virtual model of the three-dimensional part 106.

The digital integrator 126 may coordinate printing of the three-dimensional part between various remote destinations. For example, a user of the three-dimensional part 106 may utilize the digital integrator 126 to control printing of a three-dimensional part 106 from a control location in Europe to a location in Asia where the three-dimensional part 106 is printed. In this regard, a user of the three-dimensional part 106 may utilize the digital integrator 126 to control printing of a part from a control location at a first geographical location to a second geographical location where the three-dimensional part 106 is printed, and further, with a third geographical location where the three-dimensional part may be shipped to.

The digital integrator 126 may manage printing of a three-dimensional part 106 that includes multiple components by determining one or a plurality of locations and/or three-dimensional printers at which the components may be printed. In this regard, locations and/or three-dimensional printers may be specified in a hierarchal format according to priority such that if a higher priority location and/or three-dimensional printer cannot be used to print the three-dimensional part 106, a second higher priority location and/or three-dimensional printer may be used to print the three-dimensional part 106, and so forth. The hierarchy of the location and/or three-dimensional printer may be based on a variety of factors such as cost of printing, timing of printing, other print jobs in a queue, past printing activities, etc.

The digital integrator 126 may be built over a blockchain network. In this regard, the blockchain network may operate as the distributed electronic ledger 128 and provide for tracking and tracing of a print job. For example, with respect to an electronic three-dimensional printing file 104, the blockchain network may provide an electronic three-dimensional printing file owner with information such as which distributor utilized the electronic three-dimensional printing file 104, how many times the electronic three-dimensional printing file 104 was used, etc.

The digital integrator 126 may operate as a front-facing virtual inventory management system with respect to printing of three-dimensional parts using three-dimensional printers.

With respect to the distributed electronic ledger 128, a user may make an electronic three-dimensional printing file 104 available for printing. The user may upload the electronic three-dimensional printing file 104 on the distributed electronic ledger 128. Once the electronic three-dimensional printing file 104 is uploaded on the distributed electronic ledger 128, the distributed electronic ledger 128 may control transactions with respect to rights to print a three-dimensional part 106 using the uploaded electronic three-dimensional printing file 104. Thus, the distributed electronic ledger 128 may control permissions to print a three-dimensional part 106 using the uploaded electronic three-dimensional printing file 104.

With respect to the online catalogue 236 or the authorized dealer 238, these entities may upload electronic three-dimensional printing files to the distributed electronic ledger 128, and may further utilize the distributed electronic ledger 128 to control permissions to print a three-dimensional part 106 using the uploaded electronic three-dimensional printing files. In this regard, the permissions may be controlled to allow or deny a retailer such as retailer-1 and/or retailer-2 at 240 to have access to the uploaded electronic three-dimensional printing files, to thus print a three-dimensional part 106 using the uploaded electronic three-dimensional printing files.

The distributed electronic ledger 128 may also control tracking of material batches as shown at 242. In this regard, the owner of the electronic three-dimensional printing file may be ensured that the correct materials are used to manufacture the three-dimensional part 106.

Once a three-dimensional part 106 is printed, the printed three-dimensional part 106 may be delivered to a customer, for example, at 244. At the point of the delivery or otherwise, the bank payment (e.g., by the bank 204) may be controlled by the distributed electronic ledger 128.

The digital integrator 126 in conjunction with the distributed electronic ledger 128 may thus provide for virtualization and decentralization of an entire supply chain for a plurality of three-dimensional parts. For example, the digital integrator 126 in conjunction with the distributed electronic ledger 128 may provide for virtual control of a supply chain of three-dimensional parts from a first location, where a three-dimensional part is to be supplied to a second remote location where the three-dimensional part is manufactured.

This factor may be used to determine how closely to match the material properties where level-1 is the highest and level-5 is the lowest. For example, a level-1 may allow a 2% deviation, a level-2 may allow a 5% deviation, a level-3 may allow an 8% deviation, a level-4 may allow a 10% deviation, and a level-5 may allow a 15% deviation.

ascerta14 illustrates a graph of manufacturing using three-dimensional printing and non-three-dimensional printing based manufacturing to illustrate operation of a print evaluator of the system 100, according to an example of the present disclosure.

Referring to FIG. 14, the graph of manufacturing using three-dimensional printing (e.g., additive manufacturing) and non-three-dimensional printing based manufacturing (e.g., traditional manufacturing) shows that for three-dimensional printing, the cost per unit manufactured for a three-dimensional part remains constant. For non-three-dimensional printing based manufacturing, the cost per unit manufactured for a three-dimensional part varies based on the volume of the units. In this regard, a break-even point at 1400 may indicate a point where the cost per unit manufactured using three-dimensional printing and non-three-dimensional printing based manufacturing is identical. In this regard, for a number of units of a three-dimensional part that is less than the number of units at the break-even point at 1400, the print evaluator 116 may determine that such a number of units is to be manufactured using three-dimensional printing (e.g., where AM<TM as disclosed herein with respect to FIG. 2).

These rates are then factored into further calculations with respect to the non-three-dimensional printing based manufacturing costs 118 and three-dimensional printing costs 120.

FIG. 19 illustrates a user interface display for non-three-dimensional printing based manufacturing costs for non-three-dimensional printing based manufacturing to illustrate operation of the print evaluator of the system 100, according to an example of the present disclosure.

Referring to FIG. 21, based on the costs incurred in manufacturing using injection molding (see FIG. 19) and the estimated costs of three-dimensional printing (see FIG. 20), the print evaluator 116 may generate a graphical representation of the break even quantity (e.g., at 1500) beyond which it is more economical to produce parts using traditional manufacturing.

FIG. 22 illustrates details of the architecture of a distributed electronic ledger of the system 100, according to an example of the present disclosure.

Referring to FIG. 22, with respect to the distributed electronic ledger 128 that may include a blockchain network, users may be enrolled into the distributed electronic ledger 128 with their respective credentials. Once users across the network including suppliers, retailers, service owners, dealers and the payment system are enrolled, transactions may be made by the respective participants by utilizing the distributed electronic ledger 128.

At 2200, a supplier or service owner may upload a data file (e.g., including the electronic three-dimensional printing file 104) and pricing details on the distributed electronic ledger 128. The distributed electronic ledger 128 may include contract management and permission management to allow respective users to access, move, and utilize the data files for three-dimensional printing. The payment system may enable transfer of payments across the participants in a network as needed.

At 2202, the service owner may upload pricing splits (e.g., divisions) for the data files uploaded by suppliers and/or the service owner.

At 2204, the distributed electronic ledger 128 may consume the data files uploaded by the supplier.

At 2206, the service owner may transfer the data files to the dealer and/or retailer.

At 2208, the dealer may transfer the data files to the retailer.

At 2212, the distributed electronic ledger 128 may confirm consumption of data files.

At 2214, the payment system may make payments to concerned participants.

With respect to the distributed electronic ledger of FIG. 22, the distributed electronic ledger powered digital inventory may execute specific rules or validations as follows. For example, according to a rule, based on a supplier's and service provider's pricing inputs and pre-defined conditions, the payment made by either the dealer, retailer, or service provider may be divided and allocated to the respective supplier, service provider, or dealer. According to another example of a rule, the payment may be made each time a data file is executed. According to another example of a rule, the view access of specific data elements may be controlled for respective participants based on pre-defined conditions.

For the example of FIG. 22, roles of the entities including supplier, service owner, dealer, retailer, and payment system may be defined as follows.

A supplier may represent a designer of data files and sell rights, for example, to a service owner. With respect to the supplier roles, a supplier may upload a data file, view the number of times the data file has been accessed for execution, specify the charges per usage of the uploaded file, receive payments against usage of the file uploaded, and view the history of payments received. A supplier may further control aspects such as a number of data files that are subject to sale of rights, a time of printing associated with each data file, a price for licensing and/or printing associated with each data file, and a payment status.

A service owner may represent an owner of a permissioned blockchain network as disclosed herein. With respect to the service owner roles, a service owner may upload a data file, access the file uploaded by the supplier, view the number of times any file has been accessed for execution, input a number of times a file has been used into the distributed electronic ledger 128, transfer the files to dealers and retailers, receive payments on file transfers and usage of the data files, specify the charges per usage of the uploaded file, view the history of payments received, and view overall details of the files usage and availability at multiple participants. A service owner may further control aspects such as price, current ownership, inventory with each player, printing status, printing time, payment status, batch number, and terms of other transactions associated with data files.

A dealer may effectively represent a distributor. With respect to the dealer roles, a dealer may receive data files from a service owner, access the file uploaded by a supplier or service owner, view the number of times the file is procured, view the number of times the file has been accessed for execution, receive payments against usage of the file sold to a retailer, and view the history of payments received. A dealer may further control aspects such as price, current ownership (retailer), inventory with each retailer, printing status, printing time, payment status, inventory, and payment cycle for retailers.

A retailer may represent a vendor of a three-dimensional printer. With respect to the retailer roles, a retailer may receive data files from dealers and a service owner, access the file procured from dealers and a service owner, view the number of times the file been accessed for execution, make payment for a file procured for use, and view the history of payments made. A retailer may further control aspects such as price, uploader, dealer, inventory, printing time, raw material batch number, and payment status associated with the three-dimensional printing.

With respect to the payment system, the payment system may make payments for service owner, dealer, and retailer procurement of files, access the price of the file as well as any predefined payment division algorithm to transfer amounts to concerned parties, and view the history of payments done.
